Muscles of the Shoulder01:23

Muscles of the Shoulder

The muscles surrounding the shoulder girdle, including the clavicle and scapula, primarily stabilize the scapula. This stable base allows other muscles to move the humerus effectively. Scapular movements often mirror those of the humerus and extend its range of motion. For instance, raising the arm above the head would not be feasible without simultaneous upward rotation of the scapula.

Muscles that Move the Arm01:31

Muscles that Move the Arm

Nine muscles are involved in arm movements. Two of these, the pectoralis major and latissimus dorsi, originate from the axial skeleton and are called axial muscles. The other seven originate from the scapula and are called the scapular muscles.
The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...

概括

关节镜Trillat手术用于肩部不稳定导致小 subscapularis 肌肉缩在6个月,但没有力量的损失在1年. 这与Latarjet程序形成鲜明对比,后者往往导致持续的内部旋转弱点.

科学领域:

  • 整形外科手术 整形外科手术
  • 运动医学 运动医学
  • 肩部不稳定性研究研究

背景情况:

  • 肩部不稳定的Latarjet手术与持续的内部旋转强度缺陷有关.
  • 关节镜Trillat手术通过避免 subscapularis 肌肉分裂提供了一个潜在的替代方案.

研究的目的:

  • 评估关节镜Trillat手术对旋转手腕肌肉形态和强度的影响.
  • 确定关节镜Trillat手术是否会导致 subscapularis 缩或力量缺陷.

主要方法:

  • 追溯研究58名患者进行关节镜Trillat手术,以治疗慢性前肩部不稳定.
  • CT扫描评估了旋转手套肌肉截面面积 (CSA) 和脂肪透 (MMA) 在基线和6个月.
  • 内部和外部旋转器的异动力学强度测试是在手术后1年进行的.

主要成果:

  • 在6个月后, subscapularis肌肉CSA显著下降5.3%.
  • 增加的 subscapularis MMA 和减少的外部旋转器 MMA 表示肌肉变化.
  • 在1年的随访期间,内部或外部旋转器中没有发现显著的强度缺陷.

结论:

  • 关节镜Trillat手术的结果是最小的 subscapularis 肌肉缩,没有长期的力量损害.
  • 这一发现表明,关节镜Trillat手术是一种可行的选择,可以在不损害旋转手套强度的情况下稳定肩膀.
